Cerebral edema is associated with worse outcome after acute stroke; however, the minimum clinically relevant threshold remains unknown. This study aimed to identify the minimal degree of midline shift (MLS) that predicts outcome in a cohort encompassing a broad range of patients with acute stroke. ⋯ These results show that the presence of MLS predicts poor outcome and, specifically, MLS value greater than 3 mm is an important threshold across a variety of clinical settings. These findings may have relevance for the design and interpretation of future trials for antiedema therapies.

To date, specialized studies focusing on status epilepticus (SE) in anti-N-methyl D-aspartate receptor (anti-NMDAR) encephalitis are limited, and the association between the occurrence of SE and clinical outcome is controversial. This study aims to investigate the differences between patients with critical anti-NMDAR encephalitis with SE and patients who experienced epileptic seizures without SE and to evaluate the long-term disease outcomes of patients with anti-NMDAR encephalitis with SE who were admitted to the neurological intensive care unit (neuro-ICU). ⋯ Patients with critical anti-NMDAR encephalitis who present with SE have a high rate of RSE/super RSE and recover more slowly than patients without SE, but most of them will eventually achieve good long-term neurological outcomes and live seizure free after the acute phase.

Cerebral venous injury (CVI) includes injury to a dural venous sinus or major vein and leads to poorer outcomes for patients with blunt traumatic brain injury (TBI). We sought to identify the incidence, associated factors, and outcomes associated with CVI in a large national cohort. ⋯ We identified a 0.3% incidence of CVI in all-comers with blunt TBI as well as several injury-related variables that may be used to guide investigation for dural venous sinus injury. CVI was associated with poorer outcomes, with superior sagittal sinus injury having the strongest association.

Desmopressin improves hemostasis through the release of factor VIII, von Willebrand factor, and tissue plasminogen activator, and increases platelet adhesion. Neurocritical Care guidelines recommend consideration of desmopressin in antiplatelet-associated intracranial hemorrhage. Studies supporting its use have not evaluated the potential impact of desmopressin on serum sodium levels in patients receiving hypertonic saline therapy. The purpose of this study was to assess the impact of desmopressin on sodium levels and hypertonic saline effectiveness in intracranial hemorrhage. ⋯ The use of desmopressin in intracranial hemorrhage does not appear to negatively impact the ability for patients to reach goal sodium of 145-155 mEq/L. However, in patients with higher sodium goals, desmopressin may decrease hypertonic saline effectiveness.

Children supported with extracorporeal membrane oxygenation (ECMO) have been shown to be at risk for developing seizures. However, previous studies have consisted of heterogeneous patient populations. We aimed to describe the rate of seizures in pediatric patients receiving ECMO for cardiac indications and to identify risk factors for the occurrence of this complication. ⋯ Seizures in pediatric patients on ECMO for cardiac indications are common, occurring in nearly one in five patients. Seizures are frequently subclinical only and often progress to status epilepticus. Continuous electroencephalogram is therefore warranted for this patient population, especially in the setting of cardiac arrest, extracorporeal cardiopulmonary resuscitation, or severe metabolic acidosis.
